Should I manually sync FCLK for The Witcher Remake on B650MT?
When the swordplay is fluid and the FCLK is perfectly synced, the game feels incredible. The Biostar B650MT defaulted to 5200MHz memory, but the FCLK was jumping randomly between 2000-2133MHz, causing frame times to bounce between 12-28ms. I tried just turning on EXPO, but the system hard-locked after 10 minutes of gameplay. AM5 platforms are picky like that. I manually locked the FCLK at 2000MHz and nudged the memory voltage to 1.3V to ensure a strict 1:1 sync mode. RivaTuner showed the FPS range tighten from 65-90 up to a stable 82-88. I hit some memory checksum errors early on, but loosening tRFC to 500 cycles killed the instability. CPU is running at 68-75℃ and VRMs at 60-66℃. The sync mode is finally active and the gameplay is smooth.
